Application filed May 16. 1919. SerialNo. 2913695.

To HM its/tout it may comer 1i lie it known that we, Joni; Bonus, a citimen oi "1i rocee, an .l CLARENCE D. Coirr'ron, a citizen ot' the United. States, both reside ts: ot the city of New York, borough oi? Muuhatan, in the county and State of New i. r have invented a new and Improved ll rench, oi? which the following is a full, clear, and exact description.

T". invention relziiites to a wrench, and aims more particularly to provide a device of this nature which shall he peculiarly adapted for use in comiection with toggle bolts and which will greatly :htcilitato their application. to their applied position.

A. further object of this invention is the provision oi a wrench which will include 'tl'ltt't-iOil permitting of the shearing olt 1c bolt when the device is once applied. .itill further object (it this lllVOfltlOl'l is to prorithi a wrtmch oi the socket type which will readily w-e the means used to retain a to 'u hol '1 applied position, so that the h flung ot the bolt to a wall or other supporting strucimre is a coniparativel easy matter.

it other ohjcct ot the invention is the pro or. or retraining; means for pretentioe; the lrwugiureinent (it the part of: the

toggle bolt to he ti rlitened up with respect to the r-nrench.

ii at nrthcr oluect oi: the lnventlon is l the provision ot a wrench oi. this type with a removable socket, so that the same may accommodate various sizes of toggle bolts, together with the means used. to apply them to their final position.

Another object oi? the invention is to provide a socket which may be reversed, so as to accon'unodate variousv sizes of loolt-rctaiu in ruite, tl'iat it may not he necessary, in most instances, to imply an entirely differout socket.

1t final object oi? this invention is the provision oil? a wrench of this type which shall he extremely simple in construction and, consequently, economical in manufacturn.

Reference had to the attached sheet 05 dra' t which illustrate one practical our in t of our invention, and 111 wh1chlugure 1 is a sectional. trout elevation of our improved wrench;

Fig. 2 1s a sectional side V'LQW oi? the wrench wlth the handle removed from its hmly portion; and

li ies, 3, l and 5 are plan views of the various heads which may be removably at tached to the b v oi. the wrench so to accommodate various sizes of toggle bolts.

in all these ricwg like reference numerals designate :aiiinilur parts, and the reference numeral 1 indicate a handle adapted to he scour d to a shanl it which is formed with a hero El. The ion or end of the shank 2 is formed with screw threads, as indicated by the reference numeral at. Engaging the screw threads, and retained by thorn in applied p0. 'on, is a socket 5 which is also formed with abore the ends o't which. are interiorl screw threaded so as to engage the screw threads 4-, as hetore stated. The upper and. lower edges of the socket :3 are formed with grooves. such as 6, ct varying sizes, so as to be adaptable for varying sizes of nuts, such as 7, which are mounted upon the screw-thrcaded bolt 8 of the toggle bolt. These groin s (i may :turtheu heifornied with notches 6', which will permit of their being adapted to a still greater range of varying sizes of nuts.

The socket 5 is termed with an opening, such as 9, which. is adapted to have pro jecting witl'iin it a stud 1O integral with or secured to a spring arm 11 terminating in a collar 15?. slidably n'uuinted upon the shank 2, and the socket 5 is formed with a groove 11 in which the spring arm 11 seats. The tower end of the arm 11. terminates in a riuhthugled projection 13 which engages the under side oi the nut 7.

In. operation it will. be noted that the sec hot 5 may have either 0t its ends apd to the shank '2 so as toaccornn'iodate varying sizes oi. nuts 7 Assuming now that the toggle bolt has been inserted through an opening and is being retained therein by means oi a nut, such as 7, it will he perl ectly obvious that the shank oi? the uolt 8 will he presented urnmrdly within the bore 3 and that one of the grooves 6 will. engage the side walls of the nut and turn the nature with the wrench handle. :lluringr this operation the right-angled project-ion 125? will, as atorestated, engage the underside of the out 7 and prevent any displacement ot' the screw with respect to the socket 5.

The proper positioning oi? this right angled projection is secured by means of the at t 10, which will ride along the outer surliace of the socket 5 until the same enters into the opening 9, whereupon the spring arm 11 will snap the stud 10 into such opening, consequently, carrying the right-angled projection 13 to the position indicated in Fig. 2.

Should it be desired to accommodate a different sized nut than the nut 7 it will be seen that this can be readily done by simply reversing the socket 5 so as to present the opposite groove 6 to act upon the nut 7.

" Finally, it will be perceived that when the nut has been properly positioned upon the bolt 8, this bolt may be broken off at the proper length by primarily tightening the nut 7 beyond the point at which it is illustrated in the drawings, so that the bolt 8 will extend far into the bore of the shank 3. The shank may now be rocked from one extreme to the other, which will result in. a weakening of the bolt at the point of bending and the subsequent breakage of the same at this point.

It will be appreciated that various modifications of this device as illustrated may be made without in the least departing from the scope of our invention.

Having thus described our invention, what We desire to claim is:

1. A wrench, including a shank formed with a bore, a head, including a cylindrical body open at the ends and having such ends formed with grooves, providing workengaging faces, such head being reinovably and reversibly secured to the shank.

2. A wrench, including a shank, a workengaging face applied to the lower end of such shank, work-retaining means, including a collar, slidably mounted upon such shank, and a spring arm projecting downwardly from such collar, the lower end of such arm being bent inwardly and projecting below the work-engaging face wherelrv to retain the work in engagement therewith.

3. A .vrench, including a shank, a workengaging head secured to the lower end of such shank, such work-engaging head being formed with a groove in its outer face and an opening projecting from such groove inwardly into the head, a collar slidably mounted upon such shank, and a spring arm terminating in an inwardly-projecting end portion extending below the work-engaging face for retaining the 881116 in engagement with the head, such arm being adapted to seat within the groove and being provided with a stud adapted to engage the opening in such head when the lower end of the arm is in applied position.
